Les orcs doivent mourir! – Cauchemar 5 Skull Guide

If you are new to the game I recommend playing it through fully on an apprentice, then war mage.
When nightmare is available play each level on War Mage first to get 5 skulls as a practice round, then switch to the nightmare for the same run.

Standard setup:

• Steel Weaver + first skill (Death Augmenter) to get more money from kills
  (update it for either traps or archers where appropriate)
• Lightning/fire (to be used where they enter and near traps)
• Glace + épée (for trolls/hunters)
• Fire ring for ice trolls

Standard wall setting:

• Barricade leaving one space (a kill zone)
• Tar
• Masse
• Grinders
• Brimstone in front
• Spring traps behind (parfois) or archers (other times)
